SHADE-ROLLER RAISING, LOWERING, AND SUPPORTING DEVICE.

Specification of Letters Patent.

Patented July 31, 1906.

Application filed February 5,1906. Serial No. 299,449.

To all whom it may 0071166772.

Be it known that I, WILLIAM NELSON DUNN, a citizen of the United States,residing at Martinsburg, in the county of Berkeley and State of WestVirginia, have invented certain new and useful Improvements inAppliances for Lowering and Raising and Holding to any Desired Positiona Window-Shade Roller; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to an appliance for raising, lowering, and holdingwindow-shade rollers at any desired position.

One of the objects of the invention is the provision of means forsupporting the window-shade roller and for the adjustment of the samethroughout the longitudinal area of the window-frame.

A further object of the invention is the provision of means for clampingwindowshade rollers of any desired length.

Other objects of the invention are the provision of means simple inconstruction, durable, eflicient in operation, and inexpensive in themanufacture.

With these and other objects in view the invention consists in theconstruction, combination, and arrangement of parts, as will behereinafter referred to and as embodied in the accompanying drawings,which disclose the preferred form of the invention. However, it is to beunderstood that I may make such changes, variations, and modificationsas come properly within the scope of the claims hereunto appended.

In the drawings, Fi ure 1 is a front view of the window-shade rol erappliance and window-frame. Fig. 2 is a perspective view of theshade-roller support and slidable clamps.

Fig. 3 is a sectional view of one of the cordpulleys; and Fi 4 is adetail perspective view of the brac et for supporting the cordpulley,the latter being detached.

Similar reference characters indicate corresponding parts throughout theseveral views.

In the drawings the numeral 2 designates the window-frame of theordinary construction and the same forming no part of the invention, andsecured thereto at a suitable l0- cality approximate to the upper edgeof the cross-bar of the said frame and a distance from one another arebrackets 3, the latter being connected by a suitable fastening 4.

Rotatively mounted in each of the brackets 3 is a grooved pulley 5, thesame having a bearing on a detachable pin 6, carried by the said bracket3, and traveling on each of the said grooved pulleys are cords 7 and 8.The latter, however, may be in the form of wire roping, if founddesirable. One extremity of each of the said cords 7 and 8 is fastenedto slidable clamps 9, the latter having ad justment throughout thelongitudinal extent of a strip 10, which may be of any suitablematerial, though preferably of wood, and also may have any desiredthickness. Each of said slidable clamps 9 are provided. with an opening11 for receiving the terminals of the cords 7 and 8, so that the samemay be secured thereto, and also cause the clamps 9 to bind the saidstrip 10, and thereby prevent longitudinal displacement of the clampslongitudinally with respect to the strip 10. Depending from each clampis an extension 12 and 13, the former having a curved open slot 14 andthe latter having an opening 15 for the purpose of receiving theextremities of a curtain-shade roller 16 of the usual type and providedwith the shade 17.

Each of the cords 7 and 8 are of sufficient length to allow thecurtain-shade roller 16 to be positioned normally intermediate the depthof the window-frame 2, and the other terminals thereof are connected toa ring 18, the latter having secured thereto a single cord 19, providedwith a plurality of rings 20, positioned at desirable intervalsthroughout the length of the said single cord 19. At a suitable positionon the side member of the window-frame 2 is a catch member 21, which isadapted for engagement with any one of the plurality of rings 20, so asto retain the shade-roller 16 in its desired adjusted positionthroughout the extent of the windowframe 2, and there may be a number ofthese catch members 21, if found necessary.

For adjusting or positioning the shaderoller 16 it is necessary for theoperator to release any one of the plurality of rings 20, and by pullingon the single cord 19 will cause the strip 10 to be elevated and at thesame time due to the positionin of the shade-roller 16 in the adjustableor s idable clamps 11 to be raised the desired height with respect tothe extent or depth of the window-frame.

Having described the invention, what is claimed is- 1. In an applianceof the class described, a plurality of brackets having grooved pulleysIOC j ournaled therein, a strip, clamps forming split sleeves forslidable engagement with the strip and having openings in the bodythereof, depending extensions on said clamps, a shade-roller supportedby said extensions, cords secured in the openings of each of said clampsand passing over the pulleys, rings on said cords, and catches on thewindow-frame with which said rings cooperate to hold the said roller inany position, said cords engaging the openings of the sleeve adapted tobind the same on thestrip and to prevent longitudinal movement withrespect to the latter.

'2. In an appliance of the class described, a plurality of bracketshaving grooved pulleys journaled therein, a strip, slidable clamps,

each of said clamps forming a split sleeve for slidable engagement withthe strip and hav ing openings in the body thereof, a shaderollercarried by the said clamps, cords secured in the openings of each of thesaid clamps and adapted to bind the latter on the strip and preventlongitudinal movement with respect to the strip and passing over thepulleys, means carried by the cords, and catches on the window-frame forengagement with the said means to hold the shaderoller in any position.
